What is Toyota procedure for lining up center support bearing?

Lay the shaft on the bearings without the caps, check the free play on the mains thrust bearing, the shaft should spin freely , now fit the main bearing caps , working from the center out tighten the caps one at a time to 10 ft lbs turning the shaft to make sure it is still free to spin, a rear main rope seal can cause problems if not fitted right, if the shaft locks up at the 10 ft lb settings the shaft could be bent or the wrong size bearings are fitted.

did you mark the two ends of the shaft at gearbox and diff
so they lined up again
with the center bearing replacement
did you mark the two halves before separating and replacing the center bearing
then make sure they lined up again

if vibration is there
you may need to go to a diff shop and have the drive shaft balanced properly

check for the drive joint phasing and angle setting of the center bearing
mostly with center bearing , the drive shaft has to be split and the flange removed for the bearing replacement
the flange can be put back on in any position and that will throw out the s joint phasing
Take it to a drive line specialist shop and ash them to check the phasing and angles to eliminate the vibration
The vibration could have been from a bad joint and the new joint was not properly installed which will also vibrate
If you are not familiar with the term phasing It is when the joints are in direct line with each other when placed on a flat surface and allows the differentiating speeds of the crosses as they pass through the 90 degrees to cancel each other out and stop the vibration
the drive line specialist will know and explain it better as he will have the drive shaft to show you on

This isn't something that should be advised on line.

You might need a 2 piece drive shaft with a carrier bearing, or a single piece might work.

You'll need to take into consideration the length of the spline (either @ the tail shaft of the transmission or @ the carrier bearing) to make sure there is sufficient spline length to allow for the lengthening and shortening of the overall length as the rear axle moves up and down with the increase or decrease in spring loading. Also need to be aware (on a vertical plane) of the relative parallelism of the transmission output shaft and the differential input shaft.

This one can bite you big time if you don't do all your homework!

In any event, you'll probably be better of if you engage the services of a professional drive line shop in your area.

Good luck!

The center support bearing is secured to the cross-member using either a stud with an 11/16 in. nut or sometimes an 18mm nut. or it can also be sucured using a 3/8 in. bolt with a 5/8 in. bolt head and either a 15mm, 5/8", 11/16", or an 18mm nut, and GM did not stop the assembly line when they ran out of a certain nut or bolt and that is why there could be so many different ones used.

(A split drive-shaft is a balanced unit and it must be marked for proper alignment before separating the two halves or the drive shaft will no longer be in balance and will cause a vibration and early u-joint failure, and be very sure that there is a line on each half of the drive-shaft before it is separated so that the drive-shaft can be aligned re-assembled correctly)

The center support bearing should be pressed off and on the drive shaft using a hydraulic press, (a machine shop usually does not charge very much to do that) and using a hammer and a drift to replace the center support bearing is not recommended however some people do replace the center support bearing that way and a lot of the time they will damage the drive shaft or center support bearing and that will only make it more difficult and time consuming to properly install the center support bearing.

(The u-joint and the axle yoke should also be marked together before the u-joint is removed from the axle yoke so that they are installed back in the same way that they came out to prevent any drive shaft vibration)

To change the spark plug behind the steering shaft use a spark plug socket (a good spark plug socket will also have a provision for attaching a 5/8" or 16mm wrench to the end of the spark plug socket) and instead of putting an extension and a ratchet on the socket, slip the socket onto the spark plug and then use the wrench to loosen the spark plug and to tighten it, but also use a length of 3/8" fuel line and push the end of the spark plug into the fuel line and then use it to start and run down the spark plugs and also to remove the spark plugs once they have been loosened.

Did you change the carrier bearing. It will be cheap compared to a transmission and new drive shaft. Got 1 in my shop right now. Customer did not listen. Check that carrier bearing Cost $1350vs $50

On vehicles covered by this information that are equipped with a two-piece rear driveshaft assembly, the center support bearing may be removed for replacement. To be sure if your driveshaft may be serviced, check with your local parts supplier or dealer for parts availability information.

1. Matchmark and remove the rear driveshaft assembly. For details, please refer to the procedure located earlier in this section.
2. Remove the strap retaining the rubber cushion from the bearing support.
3. Pull the support bracket from the rubber cushion and the cushion from the bearing.
4. Press the bearing assembly from the halfshaft.

To install:

1. Assemble the center support bearing to the driveshaft:
   1. If removed, install the inner deflector onto the front shaft half and ***** punch the deflector at 2 opposite points to make sure it is tight on the shaft.
   2. Fill the space between the inner dust shield and bearing with lithium soap grease.
   3. Start the bearing and slinger assembly straight onto the shaft journal. Support the shaft and using a length of pipe over the splined end of the shaft, press the bearing and inner slinger against the shoulder of the front shaft half.
   4. Install the bearing retainer, the rubber cushion onto bearing, the bracket onto the cushion and the retaining strap.
   
   
2. Align and install the driveshaft assembly to the vehicle.

use a cutting wheel and cut through the bearing as far as you can without damaging the drive shaft.Then get a big hammer and a chisel drive the chisel into the cut and break the bearing.

you have to take drive shaft down,remove front yoke
and slide shaft out, replace bearing then reverse
procedure

its called a steady bearing, take the drive line behind it off then youll see a larger nut you un screw and it will all come apart from there

It could be rim or tire that is not mount and balanced try that first
